RECOlL-OPERATED MAGAZINE- GUN.

SPECIFICATION forming part of Letters Patent No. 428,813, dated May 27, 1890.

Application filed September 14, 1889. Serial No. 323,929. (No model.)

To aZZ whom it may concern.-

Be it known that I, HERMANN LEINEWEBER, a citizen of the United States, residing at South Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Magazine Fire-Arms, of which the following is aspecification.

The object of my invention is to provide a self-acting gun which, when its magazine is supplied with the ammunition and a cartridge has been brought into position for firing, will by a pull on the trigger fire the gun, then by release of the trigger withdraw a'nd eject the shell of the spent cartridge and thereupon immediately reload with a fresh cartridge, thereby to afford simplicity in the handling of the gun in shooting, and to permit all the cartridges contained in the magazine to be fired successively Without requir- 2o ing the operator to take. the gun from his shoulder or lose his aim. This object is accomplished by the construction illustrated in the accompanying drawings, in which Figure 1 is a broken and partly-sectional 2 5 view showing that portion of a gun between the stock and barrel (this being the part to which my improvement is applied) prepared to receive my improved mechanism, but which is not shown in position; Fig. 2, a similar view with a side of the casing removed and displaying in side elevation the mechanism affording my improvement; Fig. 3, a View of the same in vertical longitudinal sectional elevation, showing the parts in the relative 5 positions to which they are brought in pulling the trigger; Fig. 4, a View like that presented in the preceding figure, but showing the parts. in the relative positions they assume on'releasing the trigger. Figs. 5 and 6 are sectional views taken, respectively, on.

line 11 of Fig. 2, but somewhat enlarged, and looking in the direction of the arrow; Fig. 12, a broken perspective View of the reciprocatinglock-actuating and spring controlling and controlled carriage detail; Fig. 13, a section taken on the line 13 of Fig. 2, lookingin the direction of the arrow; and Fig. 14,'a perspective view of the pivotal lever for ejecting the spent cartridges and receiving and directing the loading of fresh cartridges.

A general description of the mechanism I have provided to carry out myinvention and of the operation is as follows: A longitudinally-reciprocating breech-block containing a spring-controlled firing-pin in linewith the bore of the barrel is locked against movement in pulling the trigger by vertically-sliding bolts actuated to rise and engage the breech-block by a pull on the trigger. The pull on the trigger also retracts the firing-pin against the force of its spring, and the resilience of the spring when released, to edect which release provision is made while the trigger is being pulled to or when it has reached the limit of its movement, shoots the pin forward to explode the cartridge. There is also connected with the trigger a reciprocating carriage below the breech-block and retracted by the pull on the trigger to raise the locking -bolts, and also to compress a spring at its forward end and one at its rear end. The forward spring is confined around a horizontally-reciprocating tube between a sliding head surrounding it normally at its forward end and alever pivoted above its fulcrum to the end of the tube, and another spring being provided inside the tube and confined around a rod projecting into the latter, the pivotal lever extending upward through a slot in the breech-block, so that 0 when the trigger is pulled it not only effects locking of the breech-block, but also compression of the spring (from the forward end of the latter) surrounding the tube, which is held from sliding backward by the pivotal 9 5 lever being coniinedin the slot of the locked breech-block.

\Vhen a cartridge in position has been fired by the shooting forward of the firing-pin, the trigger is released, permitting the resilient force of the spring in rear of the carriage to shoot it forward, thereby lowering the locking-bolts out of engagement with the sliding breech-block, and thus freeing the latter and permitting the forward compressed springaronnd the sliding tube to expand backward against the pivotal lever, which is thereby turned on its pivot and carries with it the breech-block. The backward movement of the breech-block opens the top of the chamber behind the barrel, and in moving backward it pulls the shell of the spent cartridge out of the bore upon a pivotal substantially bell-crank-shaped lever, the horizontally-disposed part of which is normally in position to receive a cartridge from the magazine'and is shaped to afford a suitable receptacle for it. As the breech-block is retracted, it trips the cartridge-holding lever and raises it to eject the shell of the spent cartridge through the opening left by the breech-block and to bring another cartridge into position to be introduced into the barrel. 7 V

The resilience of the backward-expanding spring on the sliding tube draws the latter backward, and thereby compresses in the same direction the spring inside the tube, so that when the resilient force of the firstnamed spring is exhausted andhas driven the breech-block backward to the limit of its play the spring-stop holding it at itsforward end is automatically released, permitting the inside spring toact, and by its resilience in a forward direction force the tube back to its normal or forward position, whereby it car; ries the breech-block back to its normal position, and the new cartridge, being in the path of the breech-block, is pushed into the bore of the gun-barrel.

A is a gun, between the barrel B and stock D of which is a chamber 0, afforded by two sides r, and thus open along its top and base, and which contains the mechanism involving my invention. Along the under side of the gun-barrel extends the magazine E, closed at its outer end (not shown) and leading at its opposite end into the chamber 0. The inner surfaces of the sides 0" are provided near their upper edges and longitudinally with rectangular grooves q, Fig. 1, forming guides and supports for the breech-block F, which fits between the guide-grooves, beinginserted therein from their rear end, from which, just below the grooves q, extends a web (1 having a slot (1 in its forward edge, and supporting at opposite sides of'the slot spring-studs 'n,

'and the sides '1" are further provided, verticall with recesses which intersect the grooves q, as shown, and behind the recesses q with recesses g the said recesses affording guides for the introduction of and confines for parts of the mechanism inserted into the chamber 0 below the breech-block and hereinafter described.

The breech-block F has lateral 1ongitudi-- From the forward upper end of the breechblock extends a spring-hook m, which projects into a recess m in the barrel B, when the breech-block is in its normal position, to

engage with the flange of the cartridge, as and for the purpose hereinafter explained, and opposite the spring-hook there extends from the breech-block to enter a recess m in the inner end and at the lower side of the barrel a guide-lip m G.is the firing-pin,resembling other firingpins in its general form, but involving a different construction as to details, being slotted, as shown at ac, Fig. 6, where it coincides 10ngitudinally with the slot 0 in the breech-block, and provided at its rear end with a head Z, having let into its lower side a spring-stop Z, which normally projects beyond such side. The firing-pin is housed in a suitably-formed bore in the breech-block, and is surrounded toward its rear end by a coiled spring 1*, (though the spring for actuating it may be of different form and arrangement,) confined at its rear. end in the bore by a stationary stop :20 and at its opposite end by a stop :0 on the pin G. The forward play of the firing-pin is sufficient to permit it to be projected at its pointed end beyond the orificew though the extent of the normal condition of expansion of the spring Z does not protrude it beyond that orifice, the pin having sufficient play independent of its spring to permit it to be normally housed as to its point in the breechblock and requiring its inertia after the expenditure of the inherent resilient force of the spring to protrude the point, and thereby force it into thebarrel B.

The mechanism contained in the chamber 0 below the breech-block is all supported on a suitable bed H, conforming to the shape of the open bottom of the said chamber, of which it forms the base when adjusted into place, wherein it is properly secured, as shown, and the bed H also carries the trigger-guardl and lateral upright bearings l and 1 respectively, in pairs on its opposite edges for the parts of the mechanism it. supports, the bearings 1 extending from coincidence with a transversely-perforated lug y, form ed 011 the bottom side of the bed H, just in advance of the trigger-guard. Toward the rear end of the bed, where it curves slightly to conform to the bend in the neck of the stock, it is provided with lateral flanges z, the upper edges thereof forming continuations of the planes of the lateral edges of the straight portion of the base, and the flanges z are grooved longitudinally along their inner sides near the upper edges to form guides, for a purpose too IIO

hereinafter described, extending to the ends of the flanges, wherea bearing 2' is provided, having a perforation near its upper end in line with a tubular socket 2 formed in the gunstock.

K is the reciprocating carriage, (shown clearly in Fig. 12,) comprising a head It at its a rear end, having guide-feathers k at opposite sides extending into the guide-grooves referred to as being provided in the flanges z, and a socket in its rear extremity to receive one end of a rod L, surrounded by a spring L, confined between the head k and stopz', the perforation in which stop aifords the bearing for the rear end of the rod, and from the center of the upper side of the head it an elbow 1& extends, having secured to or integral with its upper edge the rear extension of arectangular bifurcated block 7.3 the sides of which contain coincident curved slots 70 and from which sides extend parallel arms 70, terminating at their. forward extremities in inwardprojecting hooks 10 The extension k is slightly beveled toward its extremity, as shown at k".

M is the trigger, extending through the bed II, with the finger portion i inside the guard I, and the portion in the chamber 0 formed into a yoke or stirrup z", embracing the part 10 of the carriage K, and pivotally connected with the bearings 1 toward their upper ends, and between which bearings and the sides of the said part 7.3 they extend. The base of the stirrup 71 bears against the inner end of the head A; of the carriage, as shown, and on the upper surface of the extension k" is a lug 70 N N are the locking-bolts, rigidly connected together by a pin N, extending through the curved slots k in ,the carriage K, and thus flanking the latter.

O is a tube extending between the parallel arms In of the carriage K and terminating at its rear end, where it reaches normally between the vertical forward edges of the part it of the carriage in a laterally-flattened head 72, and near the base of the head is a vertically-extending rest h for a lever P, hereinafter described. A spring g surrounds the tube 0, and is confined at opposite ends, respectively, between the head It and awasher 77. loosely surrounding the tube, into which, from its forward end, extends through a perforated cap it, screwed on such end, a rod 72. Fig. 11, surrounded bya spiral spring 715 ,0011- fined between a stop h on the inner end of the rod and the perforated cap h The rod 72,3 terminates at its forward extremity in a head 7L7, at which it is fastened to lugs 77;, provided on the bed H.

The lever P is pivoted between its extremities to the head 72. of the tube 0, and is fulcrumed below its pivotal connection to the bed H and sides of the chamber 0 by a pin N passed through it and the lug g and the correspondingly-formed parts of the lower edges of the sides of the chamber 0.

In the bed H, near its forward end, is a spring-catch f, the head of which normally projects beyond the upper surface of the bed,

but which is depressed to bring it flush with such surface as the washer 7L2 passes over it by pulling the trigger, as and for the purpose hereinafter described, but springs back into its normal position as soon as the washer has passed it to hold the latter against backward movement by the force of the spring g.

B, Fig. 14, is the substantially bell-crankshaped lever or carrier for receiving from the magazine the cartridges successively and so directing them to the barrel, and in doing so.

block, and the horizontal arm extends along and rests normally upon the arms k of the carriage K, projecting somewhat beyond the forward end of the latter, where it is provided with a downward-projecting curved stop 6 and cars (2 forming lateral confines for the tapering end of a cartridge S. At the inner end of the slot e (from which the arm e should be of about the length of a cartridge) an angle-piece e is provided to afiord a back and lateral stop for the cartridge.

To adjust the parts into co-operative position, the breech-block F is first applied by introducing it with its lateral guides p into the guide-grooves q, provided in the sides 4" of the chamber 0, and when so adjusted in its normal position it reaches with its forward end against the rear end of the barrel B, whereby the spring-catch m and lip m enter, respectively, the recesses m and m Near the rear end of the breech-block in its under side, at opposite sides of the spring-stop Z in the head I, are sockets n, Fig. 7, which are located tobe slightly out of coincidence with (that is, in advance of) the spring-studs 'n,

which, as hereinafter stated, extend through the web 1 at opposite sides of the slot 1 therein, and the normal tendency of the studs is to spring and remain out of the sockets 01, into which they are pressed, however, as and for a purpose hereinafter described, by tlhe beveled end 7;. of the carriage K, through the medium of the trigger at the beginning of the pull thereon.

hen the breeclrblock has been inserted into position, as described, the parts supported on the bed H are adjusted through the open base of the chamber (1 in a mannerto pass the projecting portion of the lever I through the slot 0 in the breech-block, the lock-bolts N then entering the longer portions of the recesses q, provided in the inner sides of the chamber 0, the bearings I the shorter portions/thereof, the bearings l entering the recesses g and thelug being brought to coincide with the analogous parts y on the IIO edges of the opposite sides 02' The pin N may then be passed through the coincident perforations in the lugs y and y, and thereby also through the lever P, for which it thus vaifords'the fulcrum. After the bed H has been adjusted as described it is further secured in place, as shown, by a screw d at the rear end and a pin d at the Opposite end.

With the parts relatively adjusted in the manner described (as they are shown in Fig. 2) all the springs g, It, and L are'in their normal distended conditions, the lever P inclines forward from its fulcrum M the lockbolts N are down and thus out of engagement with the breech-block, (their connecting-pin N being at the lower extremities of the curved slots and the cartridge-lever R lies with its arm 6 fiat upon the arms is of the carriage K, and in that position extends to the base of the magazine E, which, as it may be of common construction, is not shown in detail, the construction I employ involving a tube extending below the barrel B longitudinally thereof, closed at its outer end, and communicating at its opposite end with the chamber 0 near its base, and containing a normally-distended helical spring vhaving a head which extends, when the spring is distended, to the mouth or inner end of the magazine. I

The magazine is supplied, on moving forward the slide 0 (shown in Fig. 1) in a side /','which"coversan opening coinciding with the part (2 of the lever R, by inserting, one after another, cartridges S, taper end foremost, upon. the lever, and thence forcing each by a succeeding one into the magazine, the magazine-spring always keeping the lever B, when in position to. receive it, supplied with a cartridge.

A pull on the trigger first retracts the carriage K until the hook ends 10 on the arms 70, which hooks are normally somewhat in ad vance'of the washer 71 are engaged with the latter; This much of the trigger movement wedges the beveled end 70* of the carriage underneath the spring-studs n (which, as will be noticed, are somewhat tapering at their upper ends) into the sockets n, and they hold the breech-block against retraction by the frictional strain against it while being locked by the rise of its locking-bolts N, as hereinafter described. The eifect through the medium of the carriage K of the pull on the trigger (besides that just described) is fourfold-namely, to lock the breech-block, retract and release the firing-pin, and compress the springs L and g.

The bolts N, by the backward sliding of the carriage, owing to their connecting-pin N being in the curved slots it rise and enter lateral recesses b, Figs. 2 and 6, in the breechblock, which, when the latter is in its normal position, coincide with the upper portions of the recesses q and they thus firmly lock the breech-block against retraction while the trigger is being pulled. The carriage K in its backward movement also impinges its lug k against the projecting spring-stop Z at the under side of the head Z of the firing-pin and retracts the firing-pin against its spring Z com pressing the latter untilthe stop Z isforced into the head by moving against and over the slightly-beveled forward edge of the web g which releases it from engagement with the lug k and permits the resilience of the springv Z to act to shoot the firing-pin forward and discharge a cartridge S, previously inserted into the'barrel B, with the flange or rim at itsrear end engaged by the spring-hook m. The retraction of the carriage K by the pull on the trigger also obviously compresses the rear spring L, and also the spring g, by the hook ends 70 compressing it through the medium of the washer 71, against the head of the tube 0. At the extreme limit of compression of the spring g the washer 71, passes the springstop f, which then rises and holds the washer against the compressed spring, preventing the latter from expanding against the direction' of its compression, it being prevented from expanding in the opposite direction by the hold of the lever P, which is held against backward turning on its pivot by confinement in the slot 0 of the breech-block, the

' latter being, as already explained, held against retraction by the bolts N. As soon as the firing-pin has been released and has discharged a cartridge the trigger is released.

This permits the compressed spring L to act and by its resilience force the carriage K forward, thereby lowering the locking-bolts N and disengaging them from the breech-block, which (the studs n being thereby also removed from the sockets n) is thus freed and must yield to the resilient force in a backward direction of the compressed spring g,

exerted upon it through the medium of the lever P. This obviously turns the level-P backward on its fulcrum N and slides the breechblock back, thereby opening the top of the chamber 0, and as the hookm is in advance of the rim or flange on the rear end of the cartridge the retraction of the breech-block also withdraws from the barrel the empty cartridgeshell. As the breech-block fii es back it engages the upright arms of the cartridge-holding lever R and suddenly trips the latter,thus by a quick movement raising the part c of the bell-crank on its fulcrum and causing it, through the medium of the cartridge S supported upon it, to impinge against the withdrawn spent shell and eject the latter through the breech. This rise in the cartridge-carrier also brings thesupported cartridge into line with the lip m on the breech-block (as will be seen on inspection of Fig. 4:) and the forward end of the cartridge coincident with the barrel B, while in the raised position of the carrrier R the lip 6, depending from its forward end, extends below the magazine-opening and prevents egress into the chamber 0 of another cartridge until the carrier resumes its normal position, attained with the movement of the breech-block back to its normal position, to which it is returned as follows:

The backward expansion of the spring g carries with it, in turning the lever P backward on its pivot to effect retraction of the breech-block, the tube 0 and compresses the spring 7L5 therein confined in a backward direction against the stop h on the rod 7L3 by the pressure against the forward end of that spring of the perforated cap or nut h", which obviously, being practically integral with the tube, moves with the latter, and as the nut it approaches the washer h it engages with the spring-stop f in the base of the bed II and forces it out flush with the surface of the bed, thereby releasing the washer and permitting the resilience of the spring 7r", which begins to expand as soon as the spring 9 has become inert by the expenditure of its resilient force to return, by expansion against the cap or nut 71 the tube 0 to its normal or forward position,and through thelatter pull the lever P back to its position of forward inclination and cause the lever to shoot the breech-block forward, which, in resuming its normal position of closing the breech, pushes the cartridge in its path into the barrel, thus reloading.

The firing-pin G, the play of which is sufficient, as already explained, to carry it slightly beyond the opening 00 is arrested in the return of the breech-block by impingement of the spring-stop Z against the lug k on the carriage to retract the firing-pin and hold it normally back from protrusion beyond the aperture where danger of its accidentally striking and exploding the cartridge with the advance of the breech-block is obviated.

The foregoing is a minute description of all the details of the mechanism and of their cooperation, rendered necessary by their somewhat intricate nature. It must not, however, be understood that the exact construction shown and described is indispensable as alone constituting my invention, because this I desire to be understood as claiming so broadly as to include any mechanism which will operate by a single pull on the trigger to lock the breech-block and actuate the firing-pin, and by releasing the trigger to effect automatically unlocking and retraction of the breechblock, withdrawal of the spent cartridge and its ejectment out of the top of the chamber, of which the breech-block forms the top or sliding cover, and the storage of force to produce automatically the return of the breechblock to advance it to its normal position, and in its advancement reload with a cartridge brought into position from the magazine by the retraction of the breech-block.

Obviously the mechanism shown and de scribed may be variously changed, and perhaps improved,to effect the action of the gun set forth without departing from the spirit of my invention, as, to cite one change that suggests itself to me, the manner of co-operation and construction of the springsg and h may be variously modified or simplified with reference to that described and shown to produce the desired result of retracting the breechblock and simultaneously storing power to return it with the attendant results set forth.
